How many hours of ABA therapy does my child need?

Nobody can answer that from a web page, and a provider who quotes you a weekly number before assessing your child is selling, not treating. The hours come out of an assessment by a BCBA, a behavior analyst certified by the Behavior Analyst Certification Board, and they follow the goals in the treatment plan. Published practice guidance from the Council of Autism Service Providers describes two broad shapes: focused treatment, commonly around 10 to 25 hours a week, and comprehensive treatment, commonly around 30 to 40 hours a week of direct treatment.

Who decides the number, and how?

A BCBA assesses your child first, then writes goals, then the hours fall out of the goals. The assessment looks at what your child can already do, what is getting in the way, what your family needs to change at home, and how your child learns. Only after that does a recommended intensity make sense. Ask to see the link between the two: which goals require which hours. The hour ranges published in practice guidance describe direct treatment time with your child and do not include the analyst's supervision time or your caregiver training sessions, which are separate parts of a program. If a proposal shows you one total number and no breakdown, ask for the breakdown.

What is the difference between focused and comprehensive?

Focused treatment works on a limited set of targets. That might be safety, communication, toileting, feeding, sleep, or a specific behavior that is putting your child or somebody else at risk. Comprehensive treatment works across many developmental areas at once, usually for a younger child with delays spread across language, play, social skills and daily living. In the published practice guidance, focused programs commonly sit around 10 to 25 hours a week and comprehensive programs commonly sit around 30 to 40 hours a week. Which shape fits is a clinical judgment about how many areas need work, not a judgment about how much you love your child.

Is more always better?

No. More hours is NOT automatically better, and the number that matters is the number your family can actually run. A 35-hour plan that gets cancelled three days a week delivers less than a 20-hour plan that happens every time. Look at the whole week your child is living in. Preschool or school, sleep, meals, siblings, the drive, the meltdown after the drive. A schedule that leaves no room for any of that will fail, and it will fail in a way that gets blamed on the child. Ask the BCBA what the plan protects: rest, school time, family time. Then ask what happens to each goal if you go lower. A good analyst can answer that goal by goal.

How does insurance decide?

The funder reads the assessment and the treatment plan and looks for goals that are specific and measurable, baseline data showing where your child started, a rationale for the requested intensity, and progress since the last authorization. Authorizations run for a set period and get renewed on data, which is why the reporting matters as much as the therapy. If a request comes back cut or denied, ask for the decision and the reason in writing, ask your BCBA to respond with the data behind the request, and ask what the appeal process is. Coverage rules differ by state and by plan, so read your own plan documents rather than trusting what any clinic says your plan covers.

What do I ask when the number feels wrong?

Five questions, and you are allowed to ask all of them. Which specific goals require these hours. What happens to which goal if we do fewer. What data will tell us in 90 days whether this was the right number. What is my part, and when is my training scheduled. What does this schedule look like laid over school and sleep and the rest of our week. A BCBA who can answer those in plain language is doing the job. One who answers with more hours are better, or with a number that matches the maximum your insurance will approve, has told you something. You can ask for a second opinion, and you can change providers.

• Ask for the assessment and the written treatment plan before you agree to any weekly hour count.
• Ask which specific goals require the recommended hours, and what changes if you do fewer.
• Lay the proposed schedule over your child's real week, including school, sleep and the drive.
• Ask what the caregiver training component is and when your sessions are scheduled.
